When a steam system shuts down, the remaining steam condenses into water, which takes up a much smaller volume than the original steam. This creates a vacuum, which can damage equipment if not relieved of in a timely way. Vacuums prevent gravity draining systems from working properly, which can lead to frozen condensate and burst piping.
Vacuum Breakers are simple, reliable devices that provide a positive means to automatically relieve or “break” an unwanted vacuum condition.
Available in sizes from 1/8” up to 4” NPT.
⅜” & ¾” NPT is also available with field adjustable range from ¼” to 20” (8 – 508mm) Hg Vacuum for use on closed vessels and piping systems to control induced vacuum within safe limits.
Brass, bronze or stainless steel construction with threaded connection.
Pre-set and adjustable models for steam or hot water use.
Protection of pressure vessels and piping collapse from vacuum conditions.
Prevention of freezing due to excess condensate remaining in the system.
Reduction of water hammer due to vacuum caused by control valve operation.
